Each rectifier tower is built up by 1-10 power modules.
Up to 5 Towers can be connected in a Master/Slave configuration.

With FlexKraft plating rectifier, you can achieve:

High plating quality – achieved consistently

low ripple enabling high plating accuracy
flexible/independent settings enabling high process controllability

Exceptional reliability, minimum of maintenance

proven technology, using high quality components, assembled in Sweden
modular design means production can be continued at less output in case of a module failure
minimized planned and unplanned downtime (a module can be exchanged in about 15 min)


Cost saving:

reduced energy consumption (IGBT technology)
optimized output and less scrap in production
dual mode operation enables space saving and up to 15% of the investment cost.
inventory cost optimization (one critical spare part /power module fits to the entire range of the rectifiers regardless size or manufacturing year)

Scalable power output in sync with production needs
